DNA molecules is a nucleic acid which carries genetic information for the synthesis of proteins that carry out various processes in all organisms and is found in the nucleus of a cell.
Messenger RNA on the other hand is a type of RNA that carries genetic information copied from DNA, for the purpose of protein synthesis.
DNA encodes the information necessary to produce the proteins needed by your body. To make these proteins, DNA first undergoes a process known as transcription.
Transcription is the process that takes place in the nucleus of a cell, where the information on the DNA strand is transferred to a molecules known as mRNA. This process is catalyzed by the enzyme RNA polymerase.
The mRNA is a type of RNA which carries the information from the DNA for protein synthesis. The mRNA moves from the nucleus to the cytoplasm to special organelles called ribosomes where proteins are synthesized.
